What changes compared with the 2004 Saab 9-3
- Score: 6.1 → 5.6
- New engines or gearboxes: 1.9 JTD/Multijet and 2.4 JTD
- No longer affected by: front seatbelt retractors that fail to rewind the webbing (rest of the car)
- Starts to be affected by: intake manifold flap failure (swirl effect) (1.9 JTD/Multijet and 2.4 JTD), turbocharger wear or failure (1.9 JTD/Multijet and 2.4 JTD), eGR valve blocked by carbon (1.9 JTD/Multijet and 2.4 JTD) and particulate filter (DPF) clogging in urban use (1.9 JTD/Multijet and 2.4 JTD) and 2 more

Names: 1.9 TiD 120 · 1.9 TiD 150 · 1.9 TTiD 180
- With caution
1.9 JTD/Multijet 8v (78-130 hp, 1997-2010)
78–130 hp · Z19DT
A mechanically long-lived engine according to the workshops consulted, but with known faults that should be checked: the EGR valve clogs easily in urban use and, on the Opel and Saab versions, the intake manifold flaps and the turbo can give trouble. Worth buying with a verifiable maintenance history.[2][3][4]
- With caution
1.9 JTD/Multijet 16v (140-190 hp, 2002-2010)
140–190 hp · Z19DTH
It shares the 8-valve version's EGR valve weakness and, on the Opel and Saab engines, the intake flaps, described as typical of this engine in the Opel Zafira B. With more power and, on many cars, a standard particulate filter, turbo wear and DPF clogging in urban use are added. Worth considering with a maintenance history and by checking these points.[5][6]
Faults that affect 2005 cars
- High severityFrequency: CommonIntakeIntake manifold flap failure (swirl effect)Yes: the intake manifold has flaps that create a swirl in the air at low revs, and their mechanism can seize or break with use. Two independent data sheets point to this fault as typical of Opel's 1.9 CDTI, with loss of power and the engine warning light on.
- High severityFrequency: OccasionalTurboTurbocharger wear or failureThe turbo (fixed on the basic versions, variable geometry on the more powerful ones) fails occasionally: a documented Alfa Romeo 147 needed a new turbo at around 215,000 km, and the Opel Vectra C and Zafira B report failures among their owners, although other accounts describe it as very durable.
- Medium severityFrequency: CommonEmissions controlEGR valve blocked by carbonYes: the EGR valve accumulates carbon with urban use and short journeys, which turns on the engine warning light and causes loss of power. It is one of this engine's most cited faults, documented independently on Alfa Romeo, Fiat and Opel.Repair (garage): €130–€800Appears at around 80,000 km
- Medium severityFrequency: CommonEmissions controlParticulate filter (DPF) clogging in urban useOn versions with a particulate filter, urban use with short journeys prevents regeneration from completing and the filter clogs: the warning light comes on, the car enters limp mode and consumption rises. A 30-minute motorway run every two weeks is recommended to avoid it.Repair (garage): €350–€600
- Medium severityFrequency: CommonClutchDual-mass flywheel wear on manual gearbox versionsYes: the dual-mass flywheel on manual gearbox versions wears with mileage and is usually replaced together with the clutch. On the Opel Zafira B there are several documented replacements between 105,000 and 195,000 km, one of them with a dealer invoice of around €1,900.Repair: €1,900Appears at around 105,000 km
- Low severityFrequency: OccasionalIntakeFaulty air flow meter on the 1.9 JTD / Multijet (loss of power)On the 1.9 JTD and 1.9 CDTI the air flow meter repeatedly appears among ancillary faults: loss of power. It is fixed by replacing the sensor after ruling out air leaks and the EGR.Repair (garage): €100–€300
Faults outside the engine in the 2005 Saab 9-3
- Critical severityFrequency: OccasionalBrakesBrake servo valve with shorter life from heat and reduced braking effectivenessIn May 2006, 21,613 Saab 9-3s built between July 2002 and March 2005 were recalled because a brake servo valve could wear out sooner than expected due to heat in the engine bay, reducing braking effectiveness. The valve was checked and replaced if necessary.
- High severityFrequency: OccasionalSuspensionBroken suspension springsThe Dutch APK inspection (the annual roadworthiness test) records broken or cracked springs on the Saab 9-3 saloon, accounting for between 3% and 7% of the defects Autozine lists for cars from 2004 to 2010. The page does not say whether the front or rear axle is affected.
- High severityFrequency: OccasionalSuspensionRear wheel hub bearing with incorrect heat treatment in the inner raceIn January 2006, 571 Saab 9-3s were recalled because the hardening treatment of the inner race of the rear wheel bearing may have been incorrect, which could cause a rolling noise and, in extreme cases, the hub to detach.
- High severityFrequency: OccasionalBrakesHandbrake cables that deform under load and reduce holdingIn December 2007, 320 Saab 9-3s were recalled because, due to a manufacturing deviation, the handbrake cables could deform under load, giving reduced or no holding. The fix was to replace the cables.
